METHOD OF REMOVING AIR FROM CATALYST COOLER AND APPARATUS THEREFOR Russian patent published in 2014 - IPC B01J38/04 B01J8/18 

FIELD: chemistry.

SUBSTANCE: invention relates to catalyst regeneration and specifically to a catalyst regenerator. The disclosed regenerator comprises: a housing having an inlet opening for the catalyst and combustion gas, an outlet opening for the regenerated catalyst, an outlet opening for feeding the catalyst into the cooler and an outlet opening for effluent gas; a catalyst cooler, having an inlet opening for a hot catalyst, linked to the outlet opening of said regenerator housing, which serves to feed the catalyst into the cooler, a gas distributor, an air vent, an outlet opening for the cooled catalyst and a plurality of heat-exchange pipes therein for carrying the coolant; and an air pipe which links said air vent with said regenerator housing. The invention also relates to a method for catalyst regeneration in said regenerator.

EFFECT: disclosed catalyst regenerator and regeneration method using same enable to efficiently use air for fluidising a hot catalyst in catalyst coolers equipped with regenerators.
